Summary

1. Four remarkable new species of Caryophyllaeidae from the Anglo-Egyptian Sudan are described, three of which (from Siluroid fishes) are referred to a new genus, Wenyonia --W. virilis, W. acuminata, and W. minuta--and the fourth (from Mormyrus caschive) to the original genus Caryophyllaeus--C. filiformis. The chief characteristics of the new genus are the situation of the sexual apertures in the anterior half of the body, and the elongated uterus. The family Caryophyllaeidae, after deletion of the genera Diporus, Monobothriuin, and Glaridacris, thus contains three genera--Caryophyllaeus, Archigetes, and Wenyonia--all of which are re-defined, with their known species.

2. Very young immature forms of Wenyonia occur in the same (Siluroid) host as the adult and are devoid of a ‘caudal’ appendage, whence it would appear that the life-history of these new forms is different from that of C. laticeps.

3. The three families of the Cestodaria--Caryophyllaeidae, Gyrocotylidae, and Amphilinidae--are re-defined.

4. The Cestodaria, after eliminating Sanguinicola (a Trematode ?), are provisionally grouped into two Orders: the Amphilinidea (with one family, the Amphilinidae) and the Paralinidea (with two families, the Caryophyllaeidae and the Gyrocotylidae), the latter being closely allied to the Bothriocephalidae. These two Orders are defined.

Andreas Villunger and colleagues discuss the biology of the PIDDosome multiprotein complex and recent advances that link PIDDosome-dependent CASP2 activation to p53 activation in response to extra centrosomes.

Centrosomes and cilia are essential structures for many functions in development and disease. Sascha Werner, Ana Pimenta-Marques and Mónica Bettencourt-Dias review how their structure and functions are maintained.

Marian Blanca Ramírez from the CSIC in Spain has been studying the effects of LRRK2, a protein associated with Parkinson’s disease, on cell motility. A Travelling Fellowship from Journal of Cell Science allowed her to spend time in Prof Maddy Parson’s lab at King’s College London, learning new cell migration assays and analysing fibroblasts cultured from individuals with Parkinson’s.
